I'm not sure exactly, but its similar to GTS as in you request and such,except with people you know and you can know IVs and get pokemon you can't on GTS from pokedex issues. It could also help people get things like scizor, which can be traded and back, and EV services could be done as well.

how about a lottery? people each week buy a ticket for a small price and at the end of the week a random person is drawn and they get a bunch of DT. and we have a pokemon shop so why not have a item shop? i know that if i could get my hands on certain items i could trade over my good team from soulsilver and im sure having a item shop would be good for a lot of other people on nightmare.
